FIELD OF THE INVENTION [0001] The present invention relates to a driver assisting system, a method for assisting a driver, and a vehicle incorporating the driver assisting system. DESCRIPTION OF RELATED ART [0002] JP10-166889A discloses a driver assisting system, which, when a distance to a preceding vehicle drops to a predetermined value, sets an increased magnitude of reaction force of an accelerator pedal. JP10-166890A discloses a similar driver assisting system. JP2000-54860A discloses a driver assisting system, which, when an automatic control is being carried out, sets an increased magnitude of reaction force of an accelerator pedal. US 2003/0163240 A1, published Aug. 28, 2003, discloses a driving assist system, which adjusts reaction force of an accelerator pedal upon detection of a discontinuous change in environment around a vehicle. [0003] US 2003/0060936 A1, published Mar. 27, 2003, discloses a driving assist system for assisting effort by an operator (a driver) to operate a vehicle driving traveling. This system comprises a data acquisition system acquiring data including information on vehicle state and information on environment in a field around the vehicle, a controller, and at least one actuator. The controller predicts a future environment in the field around the vehicle using the acquired data, makes an operator response plan in response to the predicted future environment, which plan prompts the operator to operate the vehicle in a desired manner for the predicted future environment, and generates a command. The actuator is coupled to an operator controlled input device to mechanically affect operation of the input device in a manner that prompts the operator in response to the command to operate the vehicle in the desired manner. [0004] There is a need for a driver assisting system in which an appropriate magnitude of risk, which a driver should perceive, is forwarded to the driver by a force applied to a driver controlled input device within the vehicle. SUMMARY OF THE INVENTION [0005] These and other needs are met by the present invention which provides a driver assisting system for a vehicle having a driver controlled input device operable by a driver and through which force may be applied to the driver. The system comprises a data acquisition section that acquires data including information on environment in a field around the vehicle and information on vehicle setting regarding how devices are set within the vehicle. The system also comprises a risk calculation section that calculates risk from the environment using the acquired data and the vehicle setting, and a control section that, accounting for the risk, determines a change in force applied to the driver via the driver controlled input device. A modification section determines a force modification, and modifies the change in force at the driver controlled input device according to the determined force modification. [0006] The foregoing and other features, aspects and advantages of the present invention will become apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0007] FIG. 1 is a block diagram illustrating hardware of one exemplary implementation of a driver assisting system according to the present invention; [0008] FIG. 2 is a perspective view of a vehicle in the form of an automobile incorporating the driver assisting system; [0009] FIG. 3 is a driver controlled device, in the form of an accelerator pedal, of the vehicle; [0010] FIG. 4 is a flow chart of a main routine; [0011] FIG. 5 is a traffic scene illustrating a preceding vehicle running in front; [0012] FIG. 6 is a flow chart of a subroutine; [0013] FIG. 7 is a table illustrating various modifications of a risk perceived (RP); [0014] FIG. 8 illustrates a map used for a parking brake (PKB) modification of a risk perceived (RP); [0015] FIG. 9 illustrates a map used for a snow mode modification of the risk perceived (RP); [0016] FIG. 10 illustrates a map used for a rainy weather modification of the risk perceived (RP); [0017] FIG. 11 illustrates a map used for a sporty mode modification of the risk perceived (RP); [0018] FIG. 12 illustrates a map used for a physique modification of the risk perceived (RP); [0019] FIG. 13 illustrates varying of an increment (dF) in reaction force (F) with different values of the modified risk perceived (RP.sub.c); [0020] FIG. 14 illustrates varying of reaction force (F) with different values of accelerator pedal stroke (S): Continue reading about Driver assisting system...
